Santa's Secret Ops team provokes a Polar Bear in the trailer for Arthur Christmas, the movie about Santa's idiot son from the makers of Wallace and Gromit.

We've been taken with this film ever since it showed off Santa's sick new UFO ride. This film appears to be all about the science behind Santa, and we like that. Here's a summary:

Arthur Christmas reveals the incredible, never-before seen answer to every child's question: 'So how does Santa deliver all those presents in one night?' The answer: Santa's exhilarating, ultra-high-tech operation hidden beneath the North Pole. But at the center of the film is a story about a family in a state of comic dysfunction and an unlikely hero, Arthur, with an urgent mission that must be completed before Christmas morning dawns

Arthur Christmas will be in theaters November 23rd (and expect to see more stuff about this film from Comic-Con next week).
